BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to multi-level building structures providingaccommodations for people.

2. Description of the Related Art

It has long been recognized that apartments, condominiums and othertypes of accommodation units can be placed in high rise buildings torealize economies not afforded for structures built as individual groundlevel structures. Various reasons have been proposed for providing suchhigh rise building accommodation units. It may be for example, that landcosts prohibit the placement of individual accommodation units at groundlevel. It may also be that to have a number of accommodation unitslocated in a single high rise structure will provide comfort, securityand convenience for persons utilizing such structures.

At the present time, for example, there are large numbers of elderlypersons needing some measure of healthcare for themselves and desirousof having dignified residences, requiring little care. For such people,it is often advantageous to live in a high rise structure withindividual accommodation units but having necessary assistance andconvenience accommodation facilities in the same structure.

Generally, cost savings result from the placement of multipleaccommodation units in a multi-level building structures. The costsavings make it more affordable for many persons to be able to reside inindividual accommodation units. Naturally, if construction costs of themulti-level structure are maintained at a minimum the structure becomesmore affordable as a residence for more people. Likewise, ifconstruction costs are kept to a minimum, service and convenienceproviders can better afford to locate in accommodation units in amulti-level structure.

With proper construction methods and the use of properly formed corewall structures, a high rise building can be constructed that willprovide for a maximum number of accommodation units in a given height ofthe building. The accommodation units can also be easily modified tomeet the needs of different users of such accommodation units.

It has long been recognized that core walls either pre-fabricated orconstructed in place, can be produced that incorporate the placement ofconnection members for plumbing, electrical, heating and ventilating andother similar systems and the use of such core walls can greatly reducethe construction costs of a building.

U.S. Pat. No. 3,707,165 discloses a plastic plumbing wall havingintegrally formed surface panels and a foamed core that encloses,supports and positions hot and cold water pipes and drain and ventpiping, along with electrical wiring.

U.S. Pat. No. 3,766,574 discloses a pre-fabricated plumbing partition.As disclosed a plumbing assembly is encapsulated in a cellularpolyurethane block. Water supply or drain nipples protruding from theblock permit two or more such partitions to be joined together to forman easily transported package unit for installation as a building wall.

In the past, core walls have included embedded distribution connectorsfor plumbing, electrical, heating and air conditioning and other similarsystems. The embedded distribution connectors are attached tocorresponding elements fed into and out of the building in which thecore wall is placed, through under-floor chases. The distributionconnectors located in the under-floor chases connect to additional mainconnector components located in vertical chases extending the height ofthe building. This means that the overall building height must includethe height of the under-floor chases.

Furthermore, with the distribution connectors embedded in a core wallconnecting through a floor to corresponding connectors in theunder-floor chase, it is necessary to penetrate the floor such thatfloor strength is weakened and sounds are easily transmitted from oneaccommodation unit to another, above or below.

U.S. Pat. No. 3,601,937 discloses a multiple story building constructionwherein spaced apart parallel foundation beams have service and sewerconduits therein and wherein a service wall unit supported on the firstfloor of the building extends upwardly beyond a second floor as a coreunit having service pipes, a sewer pipe and a vent pipe embeddedtherein. The service wall can be fabricated and then moved into positionover the foundation beams to connect the service pipes, sewer pipes andvent pipes through the corresponding pipes in the wall core.

U.S. Pat. No. 3,821,818 discloses a unitary building wall having aplurality of sets of passageways disposed therein. The passageways serveas conduits for introducing necessary utilities to dwelling units and aplurality of sets of tree-like passageways are provided. The unitarybuilding wall can be fabricated off-site and can be moved into positionwithin a supporting wall structure of a building. The building wall canbe stacked vertically.

U.S. Pat. No. 3,842,320 discloses a pre-fabricated insulated wall withelectrical circuit connectors housed therein.

U.S. Pat. No. 3,909,912 also discloses a pre-fabricated electrical wallstructure.

U.S. Pat. No. 4,919,164 discloses a pre-fabricated wall panel using wallstuds and placement of service lines and drains within the walls toextend through the wall studs. Wall studs, together with a top frameplate and a bottom frame plate form a pre-formed wall structure that ispositioned within buildings.

U.S. Pat. No. 6,438,903 discloses a panelized construction system. Thepanelized construction system of the invention is intended to provideinterior and exterior walls of an add-on structure for an existinghouse, or the like.

With the cost of land, particularly in urban areas, being high andconsistently rising, it is important to be able to construct peopleaccommodation units that will comfortably accommodate people while usinga minimum amount of such valuable land. Consequently, it has been foundvery desirable to build upward from the ground, with buildings that willsuitably accommodate people who do not need, or no longer need, largeliving spaces, as well as meeting social, personal and commercial needsof people. With high rise accommodation units, it is possible tocomfortably accommodate large numbers of people and if the constructioncosts for such buildings are maintained as low as possible, many morepeople can afford to utilize the buildings, when completed.

In the past, core walls have included embedded plumbing, electrical,heating and air conditioning and other similar connection members. Theembedded connection members of core walls are connected to correspondingdistribution connect rs fed into and out of the building in which thecore wall is placed through vertical and under-floor chases. Thedistribution connectors located in the under-floor chases attach to mainconnectors located in vertical chases extending essentially the heightof the building. The vertical chases are formed independently of thecore walls and the connection members in the core walls connect todistribution members in the under-floor chases and then penetrate thewalls of the vertical chases to connect to corresponding distributionconnectors in the vertical chases. This means that the overall buildingheight must include the height of the under-floor chases and thebuilding must be made large enough to accommodate the vertical chasesformed in the common areas.

Space for the vertical chases is normally provided in hallways or commonareas in the buildings in which the core walls are installed.

With connection members embedded in a core wall connecting through afloor to corresponding distribution connectors in an under floor-chase,it is necessary to penetrate the floor such that floor strength isweakened and sounds are easily transmitted from one dwelling unit toanother, above or below.

Even if core walls have connection members that connect through an endof the core wall to a vertical chase, the chase is generally formed withconstruction of the floor of the building and the connection members atthe end of the core wall feeding into the vertical chase, located in thehallway or other common building space.

The core wall of the present invention is constructed to accommodate usein any selected people accommodation, i.e., dwelling, office, shop, etc.

The structure of the present invention has a low ceiling heightrequirement for individual people accommodations, utilizing core wallspre-formed off-site and placed in the accommodations in a manner tofacilitate easy placement and connection of service lines, electricallines and disposal lines, for example. The core walls are constructed tohave a vertical chase and components arranged such that when placed inaccommodation units the nly penetration of the dwelling floor is at thevertical chase and the vertical chase is made to include part of thecore wall, so that additional building space is not required for aseparate vertical chase.

OBJECTS OF THE INVENTION

Principal objects of the present invention are to provide a peopleaccommodating building that will incorporate reduced height betweenfloors of the building; a reduction of floor plane penetrations thattraditionally weaken multi-level buildings; and to reduce soundtransmission between upper and lower accommodation units.

Another object is to provide a core wall with a vertical chase formedtherein so that a separate vertical chase, requiring connectors for thebuilding is not required in common space of the building.

A core wall of the invention has the necessary plumbing, electrical,heating and cooling connection members and any other such connectionmembers, embedded therein and connected to couplings at one or bothfaces of the core wall to connect to a wide variety of auxiliarycomponents, such as toilets, bathtubs, showers, sinks, heating and airconditioning and gas and electric powered appliances. In addition, thecore wall is constructed such that all of the connection members fromwithin the wall connect to corresponding main connectors in a verticalchase that is formed as a portion of the core wall. Some, or all, of theconnector members may be connected to auxiliary components in any givenpeople accommodation. For any such people accommodation some of theconnection members may not be used. The core wall also serves as apositive sound barrier between accommodation units at opposite sides ofthe core wall.

FEATURES OF THE INVENTION

Principal features of the invention include the use of a core wall thatmay be manufactured off-site or at the site of construction of amultiple story accommodation units. The core wall has exterior wallsurfaces constructed of required materials of a strength and thicknessnecessary to meet building standards in the location in which theaccommodation units are being constructed. The exterior surfaces of eachcore wall are spaced apart and connection members for plumbing,electrical, heating and air conditioning systems along with vents andother structures necessary for the comfort of people in the constructedaccommodation units are incorporated between the opposite wall surfacesof the core wall.

A vertical chase is provided between a portion of the faces of each corewall and the connection members within the core wall are attached tocorresponding main connector members extending vertically through thechase and aligned floor openings.

The connection members connect through one or both faces of the corewall to standard convenience components, such as toilets, bathtubs,showers, sinks, electrical outlets and fixtures, heating and coolingapparatus, vents and the like.

Additional objects and features of the invention will become apparent toa person skilled in the art to which the invention pertains from thefollowing drawings, detailed description and claims.

Prior Art

As shown in FIGS. 1 and 2, conventional multi-story buildings ofteninclude a floor 10 of people accommodation unit 12 and a floor 14 of apeople accommodation unit 16 positioned directly above the loweraccommodation unit 12. As shown, each accommodation unit 12 and 16includes a shower 18, a toilet 20, and a lavatory 22 as standardconvenience components in the accommodation unit.

A ceiling 24 for each accommodation unit is suspended from the floor 14above, by wires 26. The space between floor 14 and ceiling 24 serves asan under-floor chase 28 in which distribution connection members forstandard convenience components, i.e., plumbing, electrical, heating andair conditioning components are located. More specifically, a waterinlet conduit 30 extends as a connection member through a wall 32 of avertical chase 33 and into the under-floor chase 28. The water inletconduit 30 is the connected by a line 34 into a core wall 36 and to aconduit 38 extending vertically through the core wall 36. Water line 34is attached by connecting lines 40 through the core wall to the shower18, toilet 20 and lavatory 22. Drain lines 44 and 46, respectively, fromthe shower and the toilet, connect to a drain pipe 48 within the underceiling chase 28 and extend through the wall 32. The water inlet pipe 30and drain line 44 are connected to inlet and drain lines located invertical chase 33, after passing through wall 32. Other accommodationunits above and/or below accommodation unit 12 and 16, similarly havewater lines 30 and drain lines 44 and 46 extending downwardly into theunder ceiling chases positioned between the floor 14 of an upperaccommodation unit and the ceiling 24 of a lower accommodation unit andsuch pipes pass through a wall 32 to connect to pipes in the verticalchase 33.

Each core wall 36 is mounted between a floor 10 and floor 14 and holes52 are punched through the floors 10 and 14 to provide for coupling ofthe conduits 38 in the vertically stacked core walls and through thefloors 10 and 14. Clearly, other conduits, electrical lines and otherconnection components can run through the horizontal under-floor chase28, through the wall 32 and into the vertical chase 33 for connection tovertically extending connectors, i.e., pipes and elements (not shown)extending the height of the building within such vertical chase.

The Invention

In the embodiment of the invention shown in FIGS. 3-14, a slab 60 has aface 60A that serves as a floor for an accommodation unit 62 and has asurface 60B that is a ceiling for an accommodation unit 64. Another slab66 similarly has an upper surface 66A that serves as a floor foraccommodation unit 64 and a lower surface 66B that serves as a ceilingfor an accommodation unit 74 located beneath accommodation unit 64. Acore wall 68 extends between support walls 70 and 72 of the upperaccommodation unit 62 and a similar core wall 76 extends between supportwalls 78 and 80 of the lower accommodation unit 64. The core walls 68and 76 are identically constructed and each extends from the floor ofthe associated accommodation unit to the ceiling thereof.

In FIGS. 3 and 4 a lavatory 82 is suspended from a face of each corewall 68 and 76 and a rear discharge toilet 84 rests on the floor surfaceof each slab 60 and 66. A shower 86 is also mounted on the floor of eachslab 60 and 66 and has a raised shower pan 88 in the bottom of theshower.

If desired, a medicine cabinet 90, a light 92 and an exhaust fan 94 mayalso be mounted to the face of each core wall. A fire and smoke detector96 may be mounted to the face of core wall 76 and sprinklers 98,operated by actuation of detector 96, may be spaced along and projectfrom the face of the core wall. A gas line coupling 100 projects to theface of the core wall 76 and an electrical outlet 102, which mayaccommodate a variety of electrical devices, may be positioned toproject to the wall face. Clearly more than one such water or gas lineand electrical outlet may be provided at a face of the core wall.

Each core wall 68 and 76 includes a pair of spaced apart wall panels 106and 108 of required thickness and strength. The wall panel 106 and 108extend fully between the accommodation unit support walls 70, 72, 78 and80. they also extend between the ceiling and floor surfaces of theaccommodation units, such as the ceiling surface 60B of slab 60 and thefloor surface 66A of slab 66. A vertical chase 110 is formed within eachcore wall 68 and 76 and a removable access panel 112 may be provided ina wall surface 106 to allow access to the chase 110 and to facilitatecoupling of connection members and connector members. The chase 110 ineach core wall extends vertically, fully through the core wall from abottom edge to a top edge to receive vertical connector members forplumbing, electrical and venting systems. The remainder of the spacebetween wall panels 106 and 108 is filled with a structural foam core116 that embeds connection members extending into the core walls andinto the vertical chase to be connected to the vertical connectormembers. The vertical chases 110 of core walls 68 and 76 are aligned andopenings 118 provided through the slabs 60 and 66 between the alignedchases 110 allow vertically extending connector members in chases ofvertically aligned core walls to be connected.

The lavatory 82, rear discharge toilet 84 and shower 86, if any, of eachaccommodation unit, are all positioned such that their discharges willbe directed into the chase 110 of the core wall of the accommodationunit. Thus, the discharge for lavatory 82 connects to fitting 120projecting through the face of the core wall 110 and through a dischargeline connector 122 to a vertically extending waste line connector member124. The waste from toilet 84 also discharges through a coupling on theouter surface of core wall 76, into a discharge line connector 122 andinto the waste line 124 connector member. Waste water from the shower 86is discharged through a coupling on the face of core wall 76 into awaste line connection member 126. The waste line connection members 124and 126 each connect into a vertical main waste line connector member128 extending vertically through the aligned chase 110 and through slabs60 and 66 of the accommodation units.

Hot and cold water line connector members 132 and 134 extend verticallythrough the chase 110 to a mixing valve 136 that is connected byconnector lines 138 and 140 to couplings 142 and 144, respectively, ofthe control valve 146 of the lavatory 82. Similarly, hot and cold waterline connector members 150 and 152 extend vertically through the chaseto a mixer valve 154 and then through connection lines 156 and 158,respectively, to couplings 160 and 162. The couplings 160 and 162 areconnected to a mixer valve 164 of the shower 86.

Another cold water inlet line connector member 170 extends verticallythrough the chase 110 and is connected to each of the sprinklers 98spaced along the face of the core wall 76 by a connection line 172.Water meters 174 are provided in the water inlet lines and the watermeters are electrically connected to a electronic readout meter 176.Meter reader 176 is positioned on the outside of wall 70 where it can beviewed from outside the accommodation unit or accommodation units forwhich it is connected. An electrical duct connector member 178 receivesthe electrical wiring vertically through the chase 110 and the wiring isconnected via connection members to the various electrical components,including the meter 176 and electrical and telephone outlets, such asshown at 102. Telephone and internet connection members are connected toconnection members in the chase 110 and are then connected to some ofthe outlets 102 provided therefore in a surface of the core wall 76.

An exhaust duct or vent connector member 190 extends vertically throughthe chase 110 and is connected to exhaust fan 94 via a connection membersuch that air from the accommodation unit exhausted by fan 94 isdischarged through the duct 190 or is re-circulated. A gas lineconnector member 192 extends vertically through the chase 110 and aconnection line 194 interconnects the line 192 and a coupling 160projecting to a face of the core wall. A gas meter 196 in line 194 isconnected to the electronic readout meter 176 to provide for reading ofthe amount of gas passed through line 194.

The access panel 112 opens to allow access to the interior of the chase110 and is made of a suitable material that will provide soundinsulation, as well as sufficient strength. Structural foam 116 isprovided at the opposite sides of chase 110, as well as around theconnection members extending into the core wall from the chase 110 forconnection to the sprinklers electrical outlets and other componentsextending to an outside face of the core wall. The structural foam 116extends fully around the chase 110 and provides a seal at each hole 118in a floor through which the vertical connector members passed throughthe vertically aligned chases 110 are connected. It should be noted thatthe only penetration required through adjacent floors of the verticallypositioned dwelling units is the hole 118 provided to allow thevertically extending connector members through chases 110 to beconnected.

As best shown in FIGS. 8 and 9, the core walls 68 and 76 preferably eachhave gypsum board sheets 200 on opposite faces thereof. One or moresheets of oriented strand board 202 or other suitable material that willmeet code requirements, such as strong wood, metal or plastic materialis positioned inside each of the gypsum board faces. A U-shaped channelmember 204 fits over the top of each core wall and snugly against theceiling surface 60B of an upper slab 60. L-shaped brackets 206 have oneleg 208 nailed into the ceiling surface 60B and another leg 210extending into the structural foam core to be secured by nails 212inserted through the gypsum board and/or oriented strand board and theleg 208. Crown moldings 218 are provided between the ceiling 60A and theupper ends of the core walls to hide the connecting structure.

In similar fashion, a U-shaped channel 220 is provided at the bottom ofeach face of the core wall 68 and 76 and L-shaped brackets have one legnailed into the floor 66A and one leg extending into the foam material116 of the core wall. Nails 224 in the legs secure the core wall to thefloor and base moldings 226 may be provided to hide the adjustmentmeans.

FIGS. 10, 11 and 12 show various embodiments of construction of corewalls. As shown in FIG. 10, the core wall 228 has outer surfaces 230 and232 formed from gypsum board and/or other good sound insulatingmaterial. The gypsum board is placed over an oriented strand board 234and the space between the separated oriented strand boards is filledwith structural foam 116.

As shown in FIG. 11, the same construction is used for the wall core236, including the gypsum board facings 238, the inner layers 240 oforiented strand boards and structural foam material 116 between them.However, spaced apart U-shaped channel members 242 are provided as studsbetween the faces of the panel to provide additional strength to thecore wall. It will be apparent that connection members passed throughthe core wall 236 will pass through openings 246 provided in the channelmembers 242 to accommodate passage of such connection members.

FIG. 12 shows still another embodiment of core wall of the invention. Inthis embodiment, core wall 250 has the spaced apart gypsum board facing252 and oriented strand board sheets 254 separated by a structural foamcore 116 having spaced apart facing channel members 256 as studstherein. In this embodiment it will be apparent that connector memberspass through the structural foam of the core wall can pass between theopposing channel members.

FIGS. 13 and 14 show an arrangement wherein a lavatory 260, toilet 262and shower 264 or bathtub 265 are provided at each side of a core wall266. In such an arrangement a vertical chase 268 in the core wall servesto accommodate connectors for both sets of fixtures. In the embodimentshown in FIGS. 13 and 14, as well as in all other embodiments of theinvention, it is not necessary to have an under-floor chase; it is notnecessary to have a number of openings through each floor of stackedaccommodation units and sound insulation is maintained betweenaccommodation units.

With each toilet and shower or bathtub supported on a floor 60A, therear discharge line for each devise is connected through a face of thecore wall to a discharge conduit connector member in the chase.

A discharge conduit connection member 300 extends from connection withvertical discharge connector member conduit 170 in the chase 110 intothe core wall 76 between the outer panels 106 and 108. The dischargeconduit connection member 300 is sloped downwardly through the core wallto connect to the vertical discharge connector member conduit 170. Theslope of the discharge connection member conduit 300 allows otherdevices such as the sink 304 shown in FIG. 5 to be hung on the corewall, outside of the chase 110 and to have a drain line connection 202connected to sloped drain line 300 inside the core wall. Similarly,electrical lines embedded in the core wall can be connected to outletsat the face of the core wall to allow connection to other devices andappliances, such as the stove 306.

Each of the core walls disclosed is preferably constructed off site inthe same manner. Not all connection members inside the core wall usedwill necessarily connect convenience components at one or both faces ofthe core wall to connector members in the vertical chase portion of thecore wall. Nevertheless, such connection members are provided and evenif not used for an accommodation unit at the time of buildingconstruction are available for use in the event of subsequentmodification of the accommodation unit.

The chase formed in each core wall allows toilets, bathtubs and showerswhich are too heavy to hang and to be supported on a face of the corewall, to be floor mounted and supported and to be rear dischargeddirectly into the chase. At the same time, convenience devices, such asbathroom and kitchen sinks, which do not have the weight of a personplaced thereon can be secured to a face of the core wall. Those candischarge directly int a connector member in the chase or to the slopedconnection drain member in the core wall and then into the connectormember in the chase.

Without an under-floor chase requirement, a height from floor to floorof each stacked dwelling is less than that found in buildings havingunder-floor chases. As a result, the height requirement for eachaccommodation unit is greatly reduced and more construction savings arerealized as a result of such height savings.
